Influenced by the Wittgensteinian slogan “Don’t look for the meaning, look for the use,” ordinary language philosophers aimed to defuse various philosophical problems by analyzing key words in terms of what they are used to do or the conditions for appropriately using them. Although Moore, Grice and Searle exposed this error – mixing pragmatics with semantics – it still gets committed, now to a different end. Nowadays the aim is to reckon with the fact that the meanings of a great (...) many sentences underdetermine what we would normally mean in using them – even if the sentence is free of indexicality, ambiguity, and vagueness. This can be so because the sentence expresses a “minimal” proposition or even because it doesn’t fully express any proposition. Many theorists are led to defend “truth-conditional pragmatics” (or linguistic “contextualism”), to find a hidden indexical in every syntactic nook or semantic cranny, or otherwise to pay undue respect to seemingly semantic intuitions and intentions. This paper identifies various such moves and explains what’s regressive about them. (shrink)

Dispositional monism is the view that natural properties and relations are ‘pure powers’. It is objected that dispositional monism involves some kind of vicious or otherwise unpalatable regress or circularity. I examine ways of making this objection precise. The most pressing interpretation is that is fails to make the identities of powers determinate. I demonstrate that this objection is in error. It does however puts certain constraints on what the structure of fundamental properties is like. I show what a satisfactory (...) structure would be. (shrink)

This paper considers the possibility of prediction in land use planning, and the use of statistical research methods in analyses of relationships between urban form and travel behaviour. Influential writers within the tradition of critical realism reject the possibility of predicting social phenomena. This position is fundamentally problematic to public planning. Without at least some ability to predict the likely consequences of different proposals, the justification for public sector intervention into market mechanisms will be frail. Statistical methods like regression analyses (...) are commonly seen as necessary in order to identify aggregate-level effects of policy measures, but are questioned by many advocates of critical realist ontology. Using research into the relationship between urban structure and travel as an example, the paper discusses relevant research methods and the kinds of prediction necessary and possible in spatial planning of urban development. Finally, the political implications of positions within theory of science rejecting the possibility of predictions about social phenomena are addressed. (shrink)

This paper explores, in a rather schematic way, some issues having to do with the conception of causation and explanation implicit in regression analysis. I argue that (a) regression analysis does not yield lawlike generalizations but rather claims about causal connections in particular populations and that (b) regression analyses are not plausibly viewed as part of a neo-Humean program of analyzing causal claims in terms of claims about patterns of statistical association. I also argue that (c) the conception of explanation (...) implicit in regression analysis is deductive and involves the exhibition of a pattern of counterfactual dependence between mean values of the independent and dependent variables.

Is structure a fundamental and indispensable part of the world? Is the question of ontology a question about structure? Structure is a central notion in contemporary metaphysics [Sider 2011. Writing the Book of the World. Oxford: Clarendon Press]. Realism about structure claims that the question of ontology is about the fundamental and indispensable structure of the world. In this paper, I present a criticism of the metaphysics of realism about structure based on a version of Russell’s famous regress argument against (...) nominalism [Russell 1911. “On the Relation of Universals and Particular.” In Logic & Knowledge. Reprint, London: George Allen & Unwin]. First, I argue that the three general tests for the fundamentality of structure proposed by realism about structure rely on a particular empirical test for structure, namely, the so-called ‘similarity test for structure.’ Second, I argue that the similarity test is not well-founded because it leads to a vicious regress. Third, I argue that the regress affects the whole metaphysics of realism about structure, and that no structural notion can be said to be fundamental in connection with any of the other tests. Lastly, I argue that the question of ontology as a question about structure is not substantive. (shrink)

Infinite regress arguments play an important role in many distinct philosophical debates. Yet, exactly how they are to be used to demonstrate anything is a matter of serious controversy. In this paper I take up this metaphilosophical debate, and demonstrate how infinite regress arguments can be used for two different purposes: either they can refute a universally quantified proposition (as the Paradox Theory says), or they can demonstrate that a solution never solves a given problem (as the Failure Theory says). (...) In the meantime, I show that Black’s view on infinite regress arguments (1996, this journal) is incomplete, and how his criticism of Passmore can be countered. (shrink)

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

That a philosophical thesis entails a vicious regress is commonly taken to be decisive evidence that the thesis is false. In this paper, I argue that the existence of a vicious regress is insufficient to reject a proposed analysis provided that certain constraints on the analysis are met. When a vicious regress is present, some further consequence of the thesis must be established that, together with the presence of the vicious regress, shows the thesis to be false. The argument is (...) provided largely through the examination of Michael Bergmann's vicious regress argument against strong awareness internalism and a partial defense of that thesis against Bergmann.

Infinite regress arguments are part of a philosopher's tool kit of argumentation. But how sharp or strong is this tool? How effectively is it used? The typical presentation of infinite regress arguments throughout history is so succinct and has so many gaps that it is often unclear how an infinite regress is derived, and why an infinite regress is logically problematic, and as a result, it is often difficult to evaluate infinite regress arguments. These consequences of our customary way of (...) using this tool indicate that there is a need for a theory to re-orient our practice. My general approach to contribute to such a theory, consists of collecting and evaluating as many infinite regress arguments as possible, comparing and contrasting many of the formal and non-formal properties, looking for recurring patterns, and identifying the properties that appeared essential to those patterns. Two very general questions guided this work: How are infinite regresses generated in infinite regress arguments? How do infinite regresses logically function as premises in an argument? In answering these questions I clarify the notion of an infinite regress; identify different logical forms of infinite regresses; describe different kinds of infinite regress arguments; distinguish the rhetoric from the logic in infinite regress arguments; and suggest ways of improving our discussion and our practice of constructing and evaluating these arguments.

The phenomenon of regression toward the mean is notoriously liable to be overlooked or misunderstood; regression fallacies are easy to commit. But even when regression phenomena are duly recognized, it remains perplexing how they can feature in explanations. This article develops a philosophical account of regression explanations as “statistically autonomous” explanations that cannot be deepened by adducing details about causal histories, even if the explananda as such are embedded in the causal structure of the world. That regression explanations have statistical (...) autonomy was first suggested by Ian Hacking and has recently been defended and elaborated by André Ariew, Yasha Rohwer, and Collin Rice. However, I will argue that these analyses fail to capture what regression’s statistical autonomy consists in and how it sets regression explanations apart from other kinds of explanation. The alternative account I develop also shows what is amiss with a recent denial of regression’s statistical autonomy. Marc Lange has argued that facts that can be explained as regression phenomena can in principle also be explained by citing a conjunction of causal histories. The account of regression explanation developed here shows that his argument is based on a misunderstanding of the nature of statistical autonomy. (shrink)

If an argument can be reconstructed in at least two different ways, then which reconstruction is to be preferred? In this paper I address this problem of argument reconstruction in terms of Ryle’s infinite regress argument against the view that knowledge-how requires knowledge-that. First, I demonstrate that Ryle’s initial statement of the argument does not fix its reconstruction as it admits two, structurally different reconstructions. On the basis of this case and infinite regress arguments generally, I defend a revisionary take (...) on argument reconstruction: argument reconstruction is mainly to be ruled by charity (viz. by general criteria which arguments have to fulfil in order to be good arguments) rather than interpretation.

The work of Hubert Dreyfus interweaves productively ideas from, among others, Heidegger and Wittgenstein. A central element in Dreyfus' hugely influential interpretation of the former is the proposal that, if we are to—in some sense—'make sense' of intentionality, then we must recognize what Dreyfus calls the 'background'. Though Dreyfus has, over the years, put the notion of the 'background' to a variety of philosophical uses,1 considerations familiar from the literature inspired by Wittgenstein's reflections on rule-following have played an important role (...) in motivating the case for believing that we need to recognize the 'background' and thus also in identifying precisely what it is about the intentional that supposedly needs to be 'made sense of'. Dreyfus argues that what he calls 'representationalism' will land us with an unstoppable 'regress of rules'. In this paper, I first argue that there are actually two different arguments that Dreyfus invokes; I then go on to evaluate quite how, in the light of the problems that those arguments reveal, our position might be thought to be improved by our recognizing the 'background'. Given that various philosophical positions designed to deal with these problems have emerged within the Wittgensteinian literature, an obvious question to ask is whether the position that Dreyfus would have us adopt is essentially one of those positions. If it isn't, then how does it differ? There is surely a variety of ways in which such a comparison might be carried out and what I offer is only one. I argue that if, through a recognition of the 'background', we are thought to have acquired solutions to those problems, then it's not at all clear that the supposed solutions that emerge work. So I explore instead the possibility that that recognition forms part of an attempt to 'dissolve' those problems. In order to bring some clarity to that possibility I consider a number of different ways in which Dreyfus' proposals might be interpreted by drawing on ideas set out by John McDowell (and I suggest that his view of one of the 'regress' arguments is anticipated by Heidegger himself). I then identify and assess some of the consequences of adopting such McDowellian readings. My sense is that Dreyfus is on the side of the angels, so to speak. But if what is right in his proposals is to become clear, and if he is to be spared some obvious objections that those proposals may elicit, we need to be clear about just what kind of contribution those proposals are meant to make. In pursuing that clarity, I am attempting to follow through on the comparison of Wittgensteinian and Heideggerian ideas that Dreyfus and his supporters have initiated: what has yet to be clarified is how and why recognizing the 'background' will allow us to 'cope better' with the puzzles in the rule-following literature that they have cited in making a case for the need to recognize the 'background'. Ultimately, I will argue that assessing this matter may require a yet broader comparison of Wittgensteinian and Heideggerian themes, one which raises questions about what we take 'doing ontology' and 'doing phenomenology' to be.

The Language of Thought Hypothesis is often taken to have the fatal flaw that it generates an explanatory regress. The language of thought is invoked to explain certain features of natural language (e.g., that it is learned, understood, and is meaningful), but, according to the regress argument, the language of thought itself has these same features and hence no explanatory progress has been made. We argue that such arguments rely on the tacit assumption that the entire motivation for the language (...) of thought consists in explaining the explanandum that allegedly generates the regress. But this tacit assumption is simply false. The Language of Thought Hypothesis is a cogent view and one with considerable explanatory advantages. (shrink)

How should you decide what to do when you’re uncertain about basic normative principles? A natural suggestion is to follow some "second-order:" norm: e.g., obey the most probable norm or maximize expected choiceworthiness. But what if you’re uncertain about second-order norms too—must you then invoke some third-order norm? If so, any norm-guided response to normative uncertainty appears doomed to a vicious regress. This paper aims to rescue second-order norms from the threat of regress. I first elaborate and defend the claim (...) some philosophers have made that the regress problem forces us to accept normative externalism, the view that at least one norm is incumbent on all agents regardless of their normative beliefs. But, I then argue, we need not accept externalism about first-order norms, thus closing off any question of how agents should respond to normative uncertainty. Rather, we can head off the threat of regress by ascribing external force to a single second-order norm: the enkratic principle. (shrink)

In order to ward off the global threat of a regress of justification, Brandom argues that some claims in our linguistic practices must be treated as “innocent until proven guilty’, i.e. participants must be treated as prima facie entitled when making them. Examples he gives include claims such as “There have been black dogs” and “I have ten fingers”. Brandom calls this idea “the default and challenge structure of entitlement”. In On Certainty, Wittgenstein argues that there are basic certainties (“hinge (...) propositions” or “hinges”) such as “The world existed long before I was born” or “This is a tree” that cannot be meaningfully doubted because they provide the basic frameworks for our language–games in the first place. The aim of this article is threefold. First, it offers an understanding of Brandom’s philosophical project in the light of Wittgenstein’s On Certainty. Secondly, it shows how Brandom may help to elucidate some of the more mysterious passages in Wittgenstein’s “third masterpiece”. Thirdly, it outlines a sketch of a promising solution to an old philosophical riddle. (shrink)

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a regress (...) of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem. (shrink)

In this paper I argue that the infinite regress of resemblance is vicious in the guise it is given by Russell but that it is virtuous if generated in a (contemporary) trope theoretical framework. To explain why this is so I investigate the infinite regress argument. I find that there is but one interesting and substantial way in which the distinction between vicious and virtuous regresses can be understood: The Dependence Understanding. I argue, furthermore, that to be able to decide (...) whether an infinite regress exhibits a dependence pattern of a vicious or a virtuous kind, facts about the theoretical context in which it is generated become essential. It is precisely because of differences in context that he Russellian resemblance regress is vicious whereas its trope theoretical counterpart is not. (shrink)

The paper aims to elucidate in better detail than before the dispute about whether or not dispositional monism—the view that all basic properties are pure powers—entails a vicious infinite regress. Particular focus is on Alexander Bird's and George Molnar's attempts to show that the arguments professing to demonstrate a vicious regress are inconclusive because they presuppose what they aim to prove, notably that powers are for their nature dependent on something else. I argue that Bird and Molnar are mistaken. It (...) is true that dispositional monism is popularly assumed to characterize powers as dependent entities, but this is not what the arguments aim to prove. They merely aim to demonstrate that it would be absurd to assume that all properties are dependent in this way. Finally, it is argued that there is an unresolved tension in Bird's and Molnar's accounts of powers. They characterize them as being for their nature dependent on the manifestations that they are for, and yet ontologically independent of those same manifestations. Until that tension is resolved, their accounts are not equipped to remove the threat of vicious regress. (shrink)

This article looks at Galton's regression to the mean from several traditionally unrelated but interwoven venues: as a law of trait heredity; as a statistical artifact infiltrating careless research designs; as an illustration of cognitive bias. Hereditarians argue for the first of these, disputed by biogeneticists, who view R to M as a mere correlate of generational traits decline. Research designers busy themselves with the second perspective, but to explain the concept, cavalierly adduce various organismic states that sum as "error (...) variance" Research on subjective probability finds R to M in unexpected places. Across these contexts, the weight of argument falls on R to M's confounding rather than causal role in vexing data analysis. 2012 APA, all rights reserved). (shrink)

Saul Kripke recently has published an interpretation of the later Wittgenstein's rule-following problem as a "sceptical paradox," the conclusion of which is that language is impossible. In this dissertation, I document the history of the rule-following problem in Wittgenstein's writings, thereby providing a historical perspective not provided by Kripke. In chapters I and II, I develop a broadly Kantian interpretation of the epistemology of the Tractatus. My interpretation conflicts both with interpretations according to which the Tractatus implicitly embodies an empiricist (...) epistemology or no epistemology at all and with idealist readings. In chapter III, I extend the comparison between Wittgenstein and Kant, arguing that there is an important sense in which the notion of thought is fundamental in the Tractatus. My interpretation conflicts with interpretations according to which the Tractarian theory of meaning requires a mental act of "dubbing" which correlates signs and objects as well as with interpretations according to which nothing mental is presupposed. On one hand, chapters I-III can be read independently of chapters IV and V as an interpretation of some aspects of the Tractatus. On the other hand, these chapters lay the groundwork for my argument in chapter IV that the rule-following problem in the Philosophical Investigations is a general and forceful restatement of the problem of an infinite regress of interpretations to which the Tractarian theory of meaning was supposed to provide a solution. For various reasons, which I recount, Wittgenstein became dissatisfied with his early answer, and the problem reappears in his later work. Finally, in chapter V, I present and evaluate Kripke's interpretation of the rule-following problem from the historical perspective developed in the preceding chapters. I suggest that Kripke fails to see that it is a carry-over of a problem with which Wittgenstein wrestled in the Tractatus. In addition, although he recognizes that the later Wittgenstein believes that no fact or process could account for our ability to represent the world, he does not show clearly why Wittgenstein believes that this is so.

ZUSAMMENFASSUNG: Der Autor versucht das regressive Erleben vieler Patienten und Analytiker, die zu Beginn der Sitzung in unbewusste Prozesse eintauchen und zum Ende wieder auftauchen, mit dem Konzept der Mikroregression zu erfassen. Im Kontrast zu destruktiven Regressionsprozessen arbeitet er ihre Eigenart als integrative Regression heraus, als Funktionsmodus, der im Dienst des Ichs und der Therapie steht. Dabei verbindet er die Eigenart der formalen Regression und des Träumens aus der Freud’schen Psychoanalyse mit der Haltung des »dreaming« aus der Bion-Tradition. Mikroregressionen drücken (...) sich in Primärprozess-Denken aus, in sinnlichen Bildern, intensiven Emotionen, Inszenierungen und Körpererleben. Sie fördern den Auftrieb des Unbewussten und bewirken folgende Effekte: 1. Der Kontakt zu verdrängten und traumatischen Erinnerungsspuren wird erleichtert. 2. Nonverbale Erfahrungen inszenieren sich im intersubjektiven Feld und regen die emotionale Verarbeitungsfunktion des Analytikers an. 3. Symbolisierungsprozesse werden angestoßen und führen zu Gestaltungen eines analytischen Dritten. Ein klinisches Beispiel dient der Veranschaulichung dieser Vorgänge. (shrink)

Is the content of our thoughts determined by norms such as ‘if I know that p, then I ought to believe that p’? Glüer & Wikforss (2009a) set forth a regress argument for a negative answer. The aim of this paper is to clarify and evaluate this argument. In the first part I show how it (just like an argument from Wittgenstein 1953) can be taken as an instance of an argument schema. In the second part, I evaluate the relevant (...) premises in some detail, and argue that the dialectical situation is slightly more complicated than a ‘dilemma of regress and idleness’, as Glüer & Wikforss have dubbed it.

Plausibly, no agent ever performs an action without some desire to perform that action. If so, a regress argument shows that, given incompatibilism, we are only rarely free. The argument sidesteps recent objections to this thesis.

This paper uses a schema for infinite regress arguments to provide a solution to the problem of the infinite regress of justification. The solution turns on the falsity of two claims: that a belief is justified only if some belief is a reason for it, and that the reason relation is transitive.

Regress arguments have convinced many that reasoning cannot require beliefs about what follows from what. In this paper I argue that this is a mistake. Regress arguments rest on dubious (although deeply entrenched) assumptions about the nature of reasoning — most prominently, the assumption that believing p by reasoning is simply a matter of having a belief in p with the right causal ancestry. I propose an alternative account, according to which beliefs about what follows from what play a constitutive (...) role in reasoning. (shrink)

This paper presents a regress challenge to the selective psychological debunking of moral judgments. A selective psychological debunking argument conjoins an empirical claim about the psychological origins of certain moral judgments to a theoretical claim that these psychological origins cannot track moral truth, leading to the conclusion that the moral judgments are unreliable. I argue that psychological debunking arguments are vulnerable to a regress challenge, because the theoretical claim that ‘such-and-such psychological process is not moral-truth-tracking’ relies upon moral judgments. We (...) must then ask about the psychological origins of these judgments, and then make a further evaluative judgment about these psychological origins… and so on. This chain of empirical and evaluative claims may continue indefinitely and, I will argue, proponents of the debunking argument are in a dialectical position where they may not simply call a halt to the process. Hence, their argument cannot terminate, and its debunking conclusion cannot be upheld. (shrink)

The article argues that theorists who try to justify 'ought'-claims, i.e., who try to show that a standard of behavior has normative authority, will run into a regress problem. The problem is similar in structure to the familiar regress in the justification of belief. The point of the paper is not skeptical. Rather, the aim is to help theorists better understand the challenges associated with formulating a theory of normative authority.

The problem, or cluster of problems, of the unity of the proposition, along with the cluster of problems that tend to go under the name of Bradley’s regress, has recently again become a going concern for philosophers, after having for some time been regarded as primarily of historical interest. In this paper, I distinguish between the different problems that tend to be brought up under the heading of the unity of the proposition, and between different related regress arguments. I present (...) my favored solutions to these problems. (shrink)

The epistemic regress problem is about the possibility of having beliefs that are based on evidence. The problem of the criterion is about the possibility of having beliefs that are based on general standards for distinguishing what is true from what is false. These problems are similar. Each is constituted by a set of propositions about epistemically valuable relational properties—being supported by evidence and being authorized by a criterion of truth—that are individually plausible but jointly inconsistent, a paradox. The propositions (...) that constitute one problem have the same forms as the propositions that constitute the other. In particular, each problem turns on the claim that a belief can have a valuable relational property only by means of an endless regress and that this requirement cannot be satisfied. Finally, since evidence and criteria are kinds of reasons, each problem is about the possibility of having beliefs that are based on reasons. (shrink)

Die Abschaffung der Sklaverei, die Einführung sozialer Sicherungssysteme, die Sanktionierung von Vergewaltigung in der Ehe gelten gemeinhin als gesellschaftlicher Fortschritt – als ein Wandel zum Besseren.

Fortschritt, so zeigt sie, ist nicht der Vorlauf zu einem bereits bekannten Ziel, sondern der nie abgeschlossene Prozess der Emanzipation. (shrink)

The best extant statement of the epistemic regress problem makes assumptions that are too strong. An improved version assumes only that that reasons require support, that no proposition is supported only by endless regresses of reasons, and that some proposition is supported. These assumptions are individually plausible but jointly inconsistent. Attempts to explain support by means of unconceptualized sensations, contextually immunized propositions, endless regresses, and holistic coherence all require either additional reasons or an external condition on support that is arbitrary (...) from the believer's own point of view.

In this work we propose an encoding of Reiter’s Situation Calculus solution to the frame problem into the framework of a simple multimodal logic of actions.

Recent work by Peijnenburg, Atkinson, and Herzberg suggests that infinitists who accept a probabilistic construal of justification can overcome significant challenges to their position by attending to mathematical treatments of infinite probabilistic regresses. In this essay, it is argued that care must be taken when assessing the significance of these formal results. Though valuable lessons can be drawn from these mathematical exercises (many of which are not disputed here), the essay argues that it is entirely unclear that the form of (...) infinitism that results meets a basic requirement: namely, providing an account of infinite chains of propositions qua reasons made available to agents.

There are important similarities between the epistemic regress problem and the problem of the criterion. Each turns on plausible principles stating that epistemic reasons must be supported by epistemic reasons but that having reasons is impossible if that requires having endless regresses of reasons. These principles are incompatible with the possibility of reasons, so each problem is a paradox. Whether there can be an antiskeptical solution to these paradoxes depends upon the kinds of reasons that we need in order to (...) attain our epistemic goals. This article explains the problems and considers the ways in which two different conceptions of human flourishing support the value of different kinds of reasons. One conception requires reasons that allow an easy solution to these paradoxes. The other—rational autonomy—requires reasons that depend upon endless regresses. So we cannot have the kinds of fully transparent reasons required for rational autonomy. (shrink)

This paper revisits the debate between Harry Collins and Allan Franklin, concerning the experimenters’ regress. Focusing my attention on a case study from recent psychology (regarding experimental evidence for the existence of a Mozart Effect), I argue that Franklin is right to highlight the role of epistemological strategies in scientific practice, but that his account does not sufficiently appreciate Collins’s point about the importance of tacit knowledge in experimental practice. In turn, Collins rightly highlights the epistemic uncertainty (and skepticism) surrounding (...) much experimental research. However, I will argue that his analysis of tacit knowledge fails to elucidate the reasons why scientists often are (and should be) skeptical of other researchers’ experimental results. I will present an analysis of tacit knowledge in experimental research that not only answers to this desideratum, but also shows how such skepticism can in fact be a vital enabling factor for the dynamic processes of experimental knowledge generation.

Wolff’s relation to Leibniz and Kant’s relation to both are notoriously vexed questions. First, this paper argues that Wolff’s most serious departure from Leibniz consists in his (so far overlooked) rejection of the latter’s infinitism. Second, it contends that the controversies that surrounded Wolff’s early acceptance of infinite causal regress and prompted his conversion to finitism played a prominent role in shaping the theses of Kant’s Antinomies. Whereas Leibniz and the early Wolff considered infinite regress to provide support for the (...) contingency of the world and the existence of God, Wolff’s enemies condemned it as Spinozistic. After Wolff, the claim that an infinite chain of causes is impossible became the standard view among both Wolffian and anti-Wolffian metaphysicians. (shrink)

Many studies confirm the fact that women do not have sufficient knowledge about reproductive health, which is a significant problem nowadays due to the large percentage of people who suffer from infertility. A sources of knowledge from which information about health, including reproductive health, is obtained have various levels of reliability. The aim of the study was to use regression trees to find which of the analysed parameters had the greatest impact on the level of respondents’ knowledge about fertility and (...) the impact of diet on fertility. The study was conducted among women who practice dance in Max Dance studio in Białystok. The group consisted of 42 women with an average age of 26.3 years, dancing in various dance styles at various levels of proficiency. A questionnaire on lifestyle and a sources of information on fertility was used; the questionnaire also contained a knowledge test focused on reproductive health and the impact of diet on fertility, in which the questions were based on information from the latest research. Three regression trees were created for three indicators determining the level of respondents’ knowledge. The obtained results revealed certain areas that have a significant impact on the level of knowledge about reproductive health, which may require additional education. The use of the regression trees method made it possible to determine the relationships between the analysed data that were not fully visible after standard biostatistical analyses had been performed. The created trees can be useful in improving the process of disseminating knowledge about reproductive health among women of childbearing age. (shrink)

In this paper we present a collection of results related to the comparability of summands property of regressive isols. We show that if an infinite regressive isol has comparability of summands, then every predecessor of the isol has a weak comparability of summands property. Recently R. Downey proved that there exist regressive isols that are both hyper-torre and cosimple. There is a surprisingly close connection between non-recursive recursively enumerable sets and particular retraceable sets and regressive isols. We apply the theorem (...) of Downey to show that among the regressive isols that are related to recursively enumerable sets there are some with a new property. (shrink)

According to Johansson (2009: 22) an infinite regress is vicious just in case “what comes first [in the regress-order] is for its definition dependent on what comes afterwards.” Given a few qualifications (to be spelled out below (section 3)), I agree. Again according to Johansson (ibid.), one of the consequences of accepting this way of distinguishing vicious from benign regresses is that the so-called Russellian Resemblance Regress (RRR), if generated in a one-category trope-theoretical framework, is vicious and that, therefore, the (...) existence of tropes only makes sense if trope-theory is understood (minimally) as a two-category theory which accepts, besides the existence of tropes, also the existence of at least one universal: resemblance.1 I disagree. But how can that be? How can Johansson and I agree about what distinguishes a vicious from a benign regress, yet disagree about which regresses are vicious and which are benign? In this paper I attempt to answer that question by first setting out and defending the sense of viciousness which both Johansson and I accept, only to then argue that to be able to determine if a particular regress is vicious in this sense, more than features intrinsic to the regress itself must be taken into account. This is why, although the RRR as originally set out by Russell is vicious, the seemingly identical resemblance regress which ensues in a one-category (standard) trope-theoretical context is not (provided, that is, that we accept certain views about how the nature of tropes relates to the resemblance between tropes, and given that we set our theory in a truthmaker theoretical framework – all of which are standard assumptions for proponents of (the standard-version of) the trope-theory).2.

Peter Klein has taken Aristotle’s regress argument for foundationalism as a point of departure for developing a view he calls ‘infinitism’. In this paper, I offer a critique of Klein’s view. I argue for three main conclusions. First, Klein’s response to the regress argument for foundationalism is neither infinitism nor foundationalism but a distinct position I call the “unjustified foundations” view. Second, Klein’s “unjustified foundations” view is subject to some serious problems that make it inferior to foundationalism. Third, Klein’s objections (...) to foundationalism fail to knock it from its place of superiority over the “unjustified foundations” view. Before defending these three conclusions in sections 3-5, I begin with an account of the regress argument for foundationalism in section 1 and with a brief presentation of Klein’s views in section 2.
